JACOB D. ZEISLOFT, OF FOSTER, PENNSYLVANIA.

COAL-JIG.

SPECIFICATION forming part of Letters Patent No. 437,743, dated October7, 1890.

Application filed January '7, 1889. Seal No. 295,701. (No model.)

To all whom t may concern:

Be it known that I, JACOB D. ZEISLOFT, of Foster township, county ofLuzerne, in the State of Pennsylvania, a citizen of the United States,have invented certain new and useful Improvements in Coal-Jigs, of whichthe following is a specification.

My invention relates to coal jigs or washers employed for separatingslate from coal at the mines by washing with a strong upward' andintermittent current of water, the water being actuated by a movableplunger which forces the water up through the coal and slate andseparates them, holding the coal in suspension, while the -slate andother extraneous matters fall down through the perforations or openingsin the bottom.

The objects of my invention are to prevent the great waste of water andeect a better separation by improving the construction of the apparatus;and to these ends I close the end of the tank, formerly left open, toprevent the free running out of the water with the coal and retain alarge portion of it in the tank to be used again. I slope the bottom ofthe washing-chamber from the center downward to the sides, so as tothrow the greatest quantity of the coal and slate adjacent to the sidesin order that the coal may be readily thrown over into the elevationboxes, andI provide the washing-chamberwith an additional floordepressed below the main licor to catch the heavy lumps held back by thefenders.

My invention consists in the several novel features of construction andoperation hereinafter more fully described, and set forth in the claimsannexed.

The invention is constructed as follows, reference being had to theaccompanying drawings, in which- Figure 1 is a plan view. Fig. 2 is avertical longitudinal section. Fig. 3 is a vertical section on the line3 3, Figs. 1 and 2. Fig. 4 is a section on the line 4 4, Figs. 1 and 2.Fig. 5 is a transverse vertical section through the chamber 11. Fig. 6is a like view through chamber 13.

A is the tank, provided with a vertical transverse wall 1, ext-endingnearly to the bottom and forming one side of the pistonchamber, andbeing parallel to the ends 2 and at right angles to the sides 3 and 4.

5 is a frame-work supported at one end upon the wall 1, and at the otherupon the partition 6. The frame-work carries the bottom 7, inclined eachway from the center downward to the sides and provided with instersticesor large perforations S, and 9 is a secondary double-inclined bottom atthe end of the bottom 7, lying in planes below those of the sections ofthe main bottom.

B is a plunger-piston operated vertically and forcing water from thechamber 10 through under the wall 1 and upward through the bottom 7.

A partition 6 rises vertically from the bottom 9, or it may rise fromthe bottom of the tank, and is provided with a fender 11, proj ectin ginwardly, substantially as shown, and creating a chamber 13 between thispartition and the front 12 of the tank, and this chamber is alsoprovided with a doubly-inclined and perforated bottom 7 n, havingperforations 8. Gates 14 are mounted on each side at the lower ends ofthe bottom 9, through which the slate therein is discharged. The chamber13 is also provided with gates 15, controlling openings at the bottomand on each side through which the coal mixed with a small quantity ofslate is discharged with accompanying water into the elevator box or leg1G, from which it is lifted by the buckets a of the rotating elevator O,and from the fact that the buckets are placed diagonally to theperiphery of the elevator and consist merely of fiat pieces, secured atone edge, as soon as a bucket rises above the top of the side of theelevatorbox the coal and slate are discharged into the inclined chutes17, whence it is discharged through the wicket-gates 1S, which areopened and closed by the handle, as shown in Fig. 2.

It will be observed that by the use of the partition 6, which operatesas a dam, less water is permitted to enter the chamber 13 than if nosuch partition were there, and that the fender operates to retard theflow of water and to catch and hold back many pieces of heavy slatewhich would otherwise be carried over into the chamber 13. It will alsobe observed that by the use of the iiat diagonal buckets I am onlycompelled to raise the coal IOO and slate to just above the edges of thetank, thereby saving a great amount of power as compared with thecup-buckets. It will also be seen that Jthe doubly-inclined bottoms inthe main receptacle and of the slate-recep- 'tacle'and of thecoal-receptacle throw or cause the coal or slate to slide downto thesides ,and to the gates in they coal and slate chamers.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the Washing-chamber having the perforated bottom, themeans for forcing Water up through said bottom, the settling-chamberhaving the double-inclined perforated bottom located at a lower planethan the bottom of the Washing-chamber,
